IMPROVEMENT IN QUARTZ-CRUSHERS.

Specification forming part of Letters Patent No. 56,108, dated July 3,1866.

To all whom it may concern:

Be it known that I, THOMAS SHAW, of the city and county ofPhiladelphia,Pennsylvania, have invented a new and Improved Quartz-Orusher; and I hereby declare the following to be afull, clear, andexact description of the same, reference being had to the accompanyingdrawing, and to the letters of reference marked thereon.

My invention consists in the employment of heavy balls secured by chainsto a hub of a revolving axle and to be throwninto a mortar, in themanner and for the purpose as hereinafter described.

In order to enable others to use and practice my invention, I willproceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of thespecification, Figure 1 is a side view of the quartz-crusher, of which ais a board, to which is secured blocks 1), on the top of which issecured pillars c, which supports revolving shaft (I. Said shaft carrieswheel 6, to which is secured cast-iron balls f by means of chains g. his a crank, upon the propelling of which the balls are thrown intomortar i, all for the purpose as hereafter described.

Itisintended thata suitable hopper or trough be connected on one endwith themortar a, so that quartz or other rock may be thrown in by theshovelful, and that the jarring of the mortar by reason of the poundingof the balls will cause the rock to fall into the mortar.

The apparatus is put in operation in this wise. On the revolving ofwheele (which should be of large diameter to give proper effect) theballsf will be thrown out as far as chain permits by reason ofcentrifugal force. Said balls in the course of their flight will strikean opposing obstacle with force in proportion to speed of wheel.

The mortar is to be so placed that the balls will strike the center ofsame when thrown out the length of chain, in the course of whichoperation any rock or ores thrown into said mortar will receive theblows of balls, and the finer parts be dragged out when'the ball makesits exit from mortar, after which the crushed quartz or ores may besifted in the ordinary manner.

What I claim, and desire to secure by Letters Patent, is-

The employment of metal balls secured by chains to a revolving wheel,the whole constructed and operating for the purpose described.

THOMAS SHAW.
